Mounts to screen screw holes perfectly.
Do you really think that this is a good idea?
An A8 frame without any reinforcement is much to weak to hold the spool on top.
I'm sure you can twist the side stands and move the top sideways, so imo more weight on top is no option, when frame is stock and completely unmodded.
Btw. I have an Anet A8 B myself and reinforcing the frame was the first I did when printer was new.
I agree that A8 frame should be laterally reinforced.
How did you that?
